I recently heard a terrifying prediction: Advances in defence technology will change the way war is waged today as much as industrialisation did in World War I. If true – and I don’t know one way or another, my area of expertise is economics – then we could be facing casualties on an unimaginable scale, just as the mechanisation of weaponry produced in the early 20th century.
As I said, however, I am an economist, and this prediction got me to thinking: What will this transformation mean for the US and global economy? In the past, increases in military spending have acted as a kind of stimulus. But there are reasons to doubt that will happen this time, at least in the same way.
